Patrick gave the Oxford Condensed Matter Physics seminar on A needle in a needlestack – exploiting functional inhomogeneity for optimized nano-optoelectronics. In this talk, he presented on recent advances in using high-throughput spectroscopy to study nanowires for optoelectronic applications.

Tim Crothers – PhD viva in Oxford
Patrick acted as external examiner for Tim Crothers, a student with Prof. Laura Herz in Physics at Oxford University. Tim defended his thesis on Charge-carrier transport and recombination dynamics in metal halide perovskites.
UK Semiconductor Nanowire Meeting 2019
Patrick spoke and both Arturo and Stefan gave posters at the 2019 UK Semiconductor Nanowire Meeting, held at Corpus Christi College in Oxford. The event was chaired by Patrick and Michael Johnston (Oxford Physics), and it brought nearly 35 researchers from 10 universities together to discuss nanowire research in the UK.

New Publication – Distinguishing cap and core contributions to the photoconductive terahertz response of single GaAs based core–shell–cap nanowire detectors
Our recent work on single-nanowire terahertz detectors has been published in a special issue of the Lithuanian Journal of Physics, celebrating the 70th birthday of Prof. Arunas Krotkus.
In this work, Dr Kun Peng used single-nanowire terahertz detectors with different capping to understand the relative contribution of the core and cap to the detected THz signal. By tuning the cap to be thicker, it is possible to engineer these detectors to have shorter carrier lifetimes and as a result, to exhibit direct THz field detection.
UK III-V Nanowire Meeting
Patrick spoke at the UK III-V nanowire meeting in Oxford on March 20th on “Big-data for nano-wires”. This meeting brought together the UK community in nanowire growth and characterisation for a one-day workshop.
PhD student Arturo gave a poster on his most recent work related to nanowire statistics.
